In Huntsville alabama this might by a electronic church bell or this might be part of the altec giant voice system I can't get a good picture of it but there is three horns on it

As mentioned in Discord, we can tell you for a fact it is definitely a electronic carillon. These are very common on top of churches that can't afford real bells. Considering these use the speakers similar to a Master Blaster, as a lot of electronic carillons do, these are DEFINITELY church bells.

Kind of weird, but last night 02.06.17 in Lake Worth, at about 11:15pm a strange siren was heard going off for about 15 minutes. Then it stopped for about two minutes, then came back on for another ten minutes. I called the LWPD and they said that they had officers checking it out, because a ton of calls were coming in. She indicated that NAS JRB said it wasn't coming from the base, Fort Wort said it wasn't theirs, and neither did White Settlement. I know people in Azle heard it as well.

The strange part was the sound it made. I'm trying to get the video from my daughter's phone, but it was not a tornado siren. Sounded more like an old time air raid siren?? Very strange, and I cannot find any info on it online other than a few other people asking questions on their facebook pages. If I find the video, I will edit a post it.

I'm sorry, but this is far too little information to identify what make/model of siren this is. Sirens are sirens, there isn't a specific "tornado" or "air raid" siren.
